ABSTRACT:

OFDM
otherwise called orthogonal frequency division multiplexing is a modulation and a multiple access technique that can be applied to mobile communications.
OFDM or Multitone modulation as it is sometimes called is the basis for several commercial wireless applications. In OFDM the segments are according to frequency there by dividing the spectrum into a number of equally spaced tones, which are orthogonal with each other and carries a portion of user information ....etc

Definition

Multi Carrier Modulation is a technique for data transmission by dividing a high ]bit rate data stream is several parallel low bit ]rate data streams and using these low bit rate data streams to modulate several carriers. Multi Carrier Transmission has a lot of useful properties such as delay spread tolerance and spectrum efficiency that encourage their use in untethered broadband communications. OFDM is a multi carrier modulation technique with densely spaced sub carriers that has gained a lot of popularity among the bro ....etc

Orthogonal Frequency Division Multiplexing


1. INTRODUCTION
1.1. Introduction:-
Orthogonal Frequency Division Multiplexing (OFDM) is one of the latest modulation techniques used in order to combat the frequency-selectivity of the transmission channels, achieving high data rate without inter–symbol interference. The basic principle of OFDM is gaining a wide spread popularity within the wireless transmission community. Furthermore,
OFDM is one of the main techniques proposed to be employed i ....etc

Overview
Multiplexing is sending multiple signals or streams of data on an information line at the same time in the form of a single, more complex signal and then separating the signals at the receiving end.
Inverse Multiplexing is combining multiple low speed streams of data to form a single higher-speed data stream. The sending and receiving ends use an inverse multiplexer with one high speed input stream.
Analog Transmission
Each signal is assig ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

Orthogonal Frequency Division Multiplexing (OFDM)



ABSTRACT
Orthogonal Frequency Division Multiplexing (OFDM) has recently gained a lot of attention and is a promising candidate for future wireless multimedia communications due to it is resistive to frequency-selective fading and its flexibility for handling multiple data rates for Fourth Generation (4G) wireless systems also it promises data rates up to 10Mbps. A variation of OFDM is Multi-Carrier CDMA (MC-CDMA), in which ....etc
